It appears that the image generated by default from videos is 480 x 360
However on the slider that my socrates template uses, (nivo.jquery) Featured images for the slider to display properly need to be 600 x 311.
In the image editor images can only be scaled down. Is there a way to get the image generated to be 600 x 311? Im pretty new to this so if there is a way please give me step by step instructions.
